Data for Integrated Corridor Management (ICM) Analysis,
Modeling, and Simulation (AMS), and Operations
Learn More: http://www.its.dot.gov/icms/
The integrated management of freeway, arterial, transit, and parking systems within a corridor
Management of the corridor as a system, rather than the more traditional approach of managing individual assets
What is ICM?

State DOT — Freeway Management System
Bus Company — AVL System
Local Jurisdiction 2 — Traffic Signal System
ICM System (ICMS)
An ICMS is the set of procedures, processes, and information systems that support transportation system managers in making coordinated decisions involving the optimal performance of transportation networks in a corridor.
Manage demand and balance loads across the networks by facilitating Mode shifts Route shifts Departure/arrival time shifts
Respond to events with coordinated multi-agency actions Incidents Construction Special Events Weather

ICM EvaluationU.S.DOT Hypotheses Evaluation Analysis Area
• Improve Situational Awareness• Enhance Response and Control
• Technical Assessment of the Capability to Monitor, Control, and Report on the Status of the Corridor
• Better Inform Travelers • Traveler Response (also relates to Enhance Response and Control)
• Improve Corridor Performance • Quantitative Analysis of the Corridor Performance – Mobility
• Positive or No Impact on Safety • Quantitative Analysis of the Corridor Performance – Safety
• Positive or No Impact on Air Quality • Air Quality Analysis
• Have Benefits Greater than Costs • Benefit-Cost Analysis
• Provide a Useful and Effective Tool for ICM Project Managers • Evaluation of Decision Support Systems
